KATE joined her father-in-law Prince Charles on an official royal engagement for the first time yesterday at a gallery to celebrate their shared love of the arts.

Charles may be a dab hand at painting watercolours but the giggling heir to the throne found himself struggling to compete with Kate and his wife Camilla when the three had a go at other arts skills – such as cutting out lace and ironing images on to paper at the Dulwich Picture Gallery in south London.

“I’ve no idea what I’m doing,” he said, as he tried to cut out lace. “This isn’t going to work. I’m really no use at this at all.”

Kate was laughing and he said playfully: “Stop laughing at me!”

He fared little better when the three of them moved over to the ironing board.
